Arizona officials say firefighters have one of the state's three raging wildfires almost fully contained.

The blaze is 340 square miles and has burned through Arizona's Chiricahua mountains.

"For the most part, the fire was kept to a low enough intensity that the canopy is still there," said Mary Christensen, a spokeswoman for the team that has battled the fire since it broke out May 8.

"And we believe that it probably will recover quite easily, and quickly, probably after the rains this season," she added.

Fire crews are also making headway with two other major fires. The largest blaze, which stretches more than 800 square miles, is almost 60 percent contained. That fire began May 29 and has forced nearly 10,000 residents to evacuate their homes.

The third fire has been burning in southern Arizona's Huachuca Mountains since June 12 and is 59 percent contained.

"The way I would characterize it is that the momentum is beginning to swing in our direction," said Steve Frye, deputy incident commander for the team fighting the fire. "And we are able to take an offensive rather than a defensive strategy."
